Problems solved by technology

However, due to this specific shape, these types of nacelles are generally difficult to manufacture and transport, and the circular or elliptical shape does not allow efficient use of the space inside the nacelle to accommodate the different components

Embodiment Construction

[0051] In these figures, the same reference signs are used to denote matching elements.

[0052] figure 1 A perspective view showing an example of a wind turbine 1 . As shown, the wind turbine 1 includes a tower 2 extending from a support surface 3, a nacelle 4 mounted on the tower 2, and a rotor 5 coupled to the nacelle 4 at a forward region. The rotor 5 includes a rotatable hub 6 and at least one rotor blade 7 coupled to and extending outwardly from the hub 6 . For example, in the example shown, the rotor 5 includes three rotor blades 7 . However, in alternative embodiments, the rotor 5 may comprise more or less than three rotor blades 7 . Each rotor blade 7 may be spaced from the hub 6 to facilitate rotating the rotor 5 to enable kinetic energy to be converted from wind to usable mechanical energy, and subsequently electrical energy. For example, the hub 6 may be rotatably coupled to a generator 10 positioned within or forming part of the nacelle 4 ( figure 2 ) to all...

Abstract

In a first aspect, a nacelle assembly for a wind turbine is provided. The nacelle assembly is connected to a wind turbine tower through a yaw system and comprises a front region coupled to a rotor comprising a rotor hub and at least one rotor blade. The nacelle assembly further comprises a nacelle having a cover structure to house wind turbine components and an add-on wind flow deflector system. The add-on wind flow deflector system is coupled to an outside of the cover structure to guide wind flowing to the nacelle for reducing a drag of the nacelle when a wind direction is misaligned with respect to the longitudinal wind direction in a yaw system failure event.

Description

technical field [0001] The present disclosure relates to nacelle assemblies for wind turbines having a nacelle and a wind flow deflector system, and wind turbines including such nacelle assemblies. Background technique [0002] Modern wind turbines are commonly used to supply electricity into the grid. This type of wind turbine generally includes a tower and a rotor arranged on the tower. The rotor, which typically includes a hub and a plurality of blades, rotates under the influence of the wind on the blades. The rotation generates torque, which is normally transmitted directly ("direct drive") through the rotor shaft or through the use of a gearbox to the generator. In this way, the generator produces electricity that can be supplied to the grid. [0003] Most wind turbines include a yaw system for orienting the rotor of the wind turbine in the prevailing wind direction. Typically, the yaw system is held in position by brakes (eg, hydraulic calipers and / or electric bra...
